(SPEEDWAY 1)PETERBOROUGH are expected to be without Kacper Gomolski for the next few weeks after he broke his collarbone in Poland.The teenager crashed in the Polish Junior Team Championship at Poznan on Tuesday night.X-rays confirmed the break and Polish manager Krystian Plech said: “It is 100% that there is a fracture and he will probably be out of racing for a month.”It is a major blow to the Panthers who face a hectic spell with at least seven fixtures during July plus an even busier August and are now seeking a short-term replacement.(SPEEDWAY 2)SHEFFIELD will be defending their Premier League Pairs crown when the showpiece event is staged at Somerset on Friday.Ricky Ashworth and Josh Auty won the title last year for the Yorkshire side, but Auty is currently sidelined with a broken ankle so former Somerset man Shane Parker is called into the Tigers pairing.Ashworth said: “We’re lucky to have Shane in the Sheffield team this year and to be able to call on his track knowledge.“It’s a tough old line-up though and we’ll have to be riding well to go all the way, but there is no reason why we can’t defend our title.” (SPEEDWAY 3)LEICESTER have called-up Dudley teenager Ashley Morris for their trip to Sheffield on Thursday evening.Morris has been in good form for the Heathens in the National League this year and gets his chance with the Premier League new-boys following a scaphoid injury to their Australian reserve John Oliver.Promoter David Hemsley said: “I watched Ashley complete a number of practice laps of our track on Friday and was impressed with his attitude and the way he adapted so quickly having never ridden here before. “The fixture at Sheffield gives me an opportunity to assess Ashley in a competitive meeting at this level.”(SPEEDWAY 4)DUDLEY moved to within a point of the National League leaders after a thumping 59-34 win over the Isle of Wight at Monmore Green.Skipper Jon Armstrong topped the Heathens scorechart with a 13+1 haul and Kyle Newman raced to an unbeaten 11+1 as the former Cradley club closed in on Belle Vue and the Scunthorpe/ Sheffield outfit.Boss Will Pottinger said: “I’m pleased, very pleased. We all rode very well and it sets us up nicely for some important meetings over the next few days, starting at Newport on Friday.“We have picked up points in all six league meetings so far and if we can keep the scoreboard ticking over then we will reach the play-offs. Then anything can happen!”(FIXTURES) THURSDAY JUNE 23:SKY SPORTS ELITE LEAGUE: Birmingham v Peterborough 7.30PREMEIR LEAGUE: Ipswich v Newcastle 7.30, Redcar v Rye House 7.30, Sheffield v Leicester 7.45STEVE JOHNSTON FAREWELL: Swindon 7.30FRIDAY JUNE 24:PREMIER LEAGUE PAIRS: Somerset 7.30NATIONAL LEAGUE: Newport v Dudley 7.30SATURDAY JUNE 25BRITISH GRAND PRIX: Cardiff 5pmSUNDAY JUNE 26:PREMIER LEAGUE: Rye House v Berwick 2pmNATIONAL LEAGUE: Mildenhall v Buxton 5pmNATIONAL LEAGUE KO CUP S/F 1st leg: Stoke v Dudley 3pmWELSH OPEN: Newport 1pm
